A bedbug Two butterflies of the genus Erebia sucking fresh blood from a sock. Hematophagy (sometimes spelled haematophagy or hematophagia) is the practice by certain animals of feeding on blood (from the Greek words αἷμα haima "blood" and φαγεῖν phagein "to eat").
Chupacabra killings were soon associated with a seemingly untouched animal carcass other than puncture wounds which were said to be used to suck the blood out of the victim. Reports of such killings began to spread around and eventually out of the country, reaching areas such as Mexico , Brazil , Chile , and the Southern area of the United States .
The prey is usually sucked in and swallowed whole. Some Rhynchobdellida however suck the soft tissues from their prey, making them intermediate between predators and blood-suckers. [38] Leech attacking a slug. Blood-sucking leeches use their anterior suckers to connect to hosts for feeding.
Their food source is the blood of other animals, a dietary trait called hematophagy. Three extant bat species feed solely on blood: the common vampire bat (Desmodus rotundus), the hairy-legged vampire bat (Diphylla ecaudata), and the white-winged vampire bat (Diaemus youngi). Two extinct species of the genus Desmodus have been found in North ...
Most of the 130 or more species of this subfamily feed on vertebrate blood; a very small portion of species feed on invertebrates. [2] [3] They are mainly found and widespread in the Americas, with a few species present in Asia and Africa. These bugs usually share shelter with nesting vertebrates, from which they suck blood.
The common name of many of these species, vampire moth, refers to the habit that they have of drinking blood from vertebrates. According to a recent study, some of them (C. thalictri) are even capable of drinking human blood through skin. [2] [3] However, the moths are not thought to cause any threat to humans. [4]
Fleas are wingless insects, 1.5 to 3.3 millimetres (1 ⁄ 16 to 1 ⁄ 8 inch) long, that are agile, usually dark colored (for example, the reddish-brown of the cat flea), with a proboscis, or stylet, adapted to feeding by piercing the skin and sucking their host's blood through their epipharynx.
Medicinal leeches have three jaws (tripartite) that resemble saws, on which are approximately 100 sharp edges used to incise the host. The incision leaves a mark that is an inverted Y inside of a circle. After piercing the skin, they suck out blood while injecting blood thinners similar to Anophelins; anticoagulants . [4]
